There are two non-negative integers x, y. For each operation, you can select a number to 1 and then another number will +1. During the operation, you should ensure that x, y are non-negative. After some operations, we can easily work out the maximum value of x2 + y2 by the adjustment method we learned in middle school. Now, you have a new operation: you are given three non-negative integers x, y, z. For each operation, you can select two numbers to 1 and then another number will +2. During the operation, you should also ensure that x, y, z are non-negative. After some operations, what is the maximum value of x2 + y2 + z2 ?
There are two non-negative integers x, y. For each operation, you can select a number to −1 and then another number will +1. During the operation, you should ensure that x, y are non-negative. After some (possibly zero) operations, we can easily work out the maximum value of x2 + y2 by the adjustment method we learned in middle school.
